Undercover NOPD detectives nabbed a man Tuesday night who they say sold them fake cocaine on Bourbon Street. After police arrested John Cooper, 35, and found he was selling fake cocaine, Ecstasy, marijuana and heroin, he was booked into the Orleans Parish jail on four counts of distributing false narcotics, records show.

In a New Orleans Police Department arrest report, Detective Kurt Eischen wrote a narrative of the cops' encounter with Cooper in the 400 block of Bourbon Street, on Tuesday about 11:35 p.m. Noticing Cooper talking to passing pedestrians, Eischen wrote, he approached Cooper and asked if he could borrow a lighter.

"Yeah bro, and I also have party favors," Cooper replied. "What kind of party favors do you have on you?" Eischen asked. "I have coke, Ecstasy, and some weed, but I can't sell you the weed because I have to bring it to a girl at Rick's," Cooper said, according to the report.

"How much for, like, a gram of coke?" Eischen asked. "I have an eight ball on me, but I have to bring that to another girl," Cooper said, according to the report. "I have a gram on me of some good s--- that I can give you for $60."

"Bro, last time I bought some coke out here it was some fake a-- s---," Eischen said. "How do I know yours is legit?" "You gotta stop buying your drugs from black guys," Cooper said. "They always have fake s---."

Eischen agreed to buy the $60 gram of cocaine, but, he told Cooper, first he needed to get cash from an ATM.

"Use the one in the daiquiri shop. I will wait right outside and when you get the cash, we will walk down the street a bit, 'cause there are way too many cops out here," Cooper said, according to the report.

Once Eischen and his colleague, Detective Chris Laborde, pretended to get cash out, they walked with Cooper down St. Louis Street toward North Rampart Street, the report says.

Cooper removed a white sock from inside the front of his pants and pulled out several individually wrapped bags of "white powder, multicolored pills and green vegetable matter," according to the report.

Cooper then asked, "You sure you just want the gram?" "Yeah, that's all we have money for," Eischen said. "OK, here you go," Cooper said, as he handed Eischen the smaller of the two white bags.

At that point, the report says, Eischen and Laborde displayed their NOPD badges and told Cooper they were police officers. Laborde handcuffed Cooper, advised him of his Miranda rights, and took his white sock filled with suspected drugs. Police also confiscated $90 they found in Cooper's shorts.

"Man, everything in the bag is fake," Cooper said. "Not even the weed is real."

Police performed a field test on the suspected narcotics in the sock and found they were all fake. What Cooper had described as cocaine, Ecstasy, marijuana and heroin all tested negative for those substances, the report says.
